In our post-tensioning activity, we have done this by conducting ambitious and focused R&D programmes in stay-cable systems (SSI 2000), automatic stressing equipment (AMS), high- performance grout (HPI) and anchorages (CS 2000). To enhance our capabilities in foundations, we have developed specific products like destructible joints for deep diaphragm walls, and high-tech friction barrettes implemented with a new cutter in Hong Kong. 3 Our goal is to offer the construction industry a wide and diversified range of advanced technologies throughout our network, relying on local experts who are ready to assist our clients swiftly and efficiently. Our newly created subsidiary in India is a typical example of our diversification strategy. In the space of just four years, we have supplied not only post-tensioning for civil works, but also nuclear applications, building solutions, retained earth and soil anchors as well as precasting and erection services. All the staff is local. Its members have been trained in Singapore, Hong Kong and Europe, and they have the full support of all our specialists. India is on the move and now helping other subsidiaries with new best practices. Our entire network will benefit from these improvements, since at VSL-Intrafor, expertise is a client- oriented value to be shared.

    Cable-stayed bridge From Wikipedia, the free encyclopedia Cable-stayed bridge The Rio-Antirrio bridge in Greece Ancestor Suspension bridge Related None Side-spar cable-stayed bridge, Self- Descendant anchored suspension bridge, cantilever spar cable-stayed bridge Pedestrians, bicycles, automobiles, Carries trucks, light rail Span range Medium Steel rope, post-tensioned concrete Material box girders, steel or concrete pylons Movable No Design effort medium Falsework Normally none required A cable-stayed bridge is a bridge that consists of one or more columns (normally referred to as towers or pylons), with cables supporting the bridge deck. There are two major classes of cable-stayed bridges: In a harp design, the cables are made nearly parallel by attaching them to various points on the tower(s) so that the height of attachment of each cable on the tower is similar to the distance from the tower along the roadway to its lower attachment. In a fan design, the cables all connect to or pass over the top of the tower(s). Compared to other bridge types, the cable-stayed is optimal for spans longer than typically seen in cantilever bridges, and shorter than those typically requiring a suspension bridge. This is the range in which cantilever spans would rapidly grow heavier if they were lengthened, and in which suspension cabling does not get more economical, were the span to be shortened. History of development Cable-stayed bridge by the Renaissance polymath Fausto Veranzio, from 1595/1616 Cable-stayed bridges can be dated back to 1595, where designs were found in a book by the Venetian inventor Fausto Veranzio, called Machinae Novae.
